Composite map using multiple UV channels?

[Anonymous]

Okay, so I'm trying to add an overlay onto an existing texture. (I can't get the UVs for the latter to stick during rendering, but that's a different issue.)

The problem is that both of these take up the diffuse map slot, requiring a composite map, and both use separate UV channels, which I can't seem to get to work on composite maps no matter what I try - it won't use anything but #1. Is there a way to use both?

You set the UV Channels on the maps that you apply to the layers in a Composite map, not in the Composite map or its layers.

I'm trying to use the Composite Map to "decal" a stamp over a suface material. Samab, can you restate your suggestion a little differently. What you said is very confusing, not being in your head. It's sort of like saying " you take the boat out on the water, but not on the water it's on."

What are you specifically trying to say?

if more then one uv channels used in material - viewport shows only 1st channel (

But there is a workaround. You must switch 'preview in viewport' button OFF for material and turn this option ON for composite map, where multiple channels are used.

It will not respect blending modes, only raw mix

A composite map does not have its own UV channel.

But a Composite map does have layers, those layers can contain other maps that can have their own individual UV channels.

Problem is viewport can't show all uv channels when preview for material is turned on.

Need to switch on preview @ composite map instead. However this doesn't affect render. Render is capable to handle all channels.

samab, Understood. Thanks for clarifying that.
